[Enhancement] Correlation Id support

[Sylwekqaz]

Hi,

Would be nice to have support for correlation id.
Correlation id token help to group logs events for scope (e.g. request).

It would be nice to have:

• Preview correlation id in list view
  • Color correlation id with same color for matching tokens on list view
• Ability to configure transform for correlation id in ~/.json-log-viewer like message or level
• Shortcut for filter logs with same correlation id that current selected/viewed log
